Hello Armando,

Thank you for posting in our community.

Currently, the default behavior of the Resizing feature (when allowDoubleClickToResize option is set to true)is to resize the column according to the containing data.

Having in mind the sample provided I assume that you are looking for a way to set a minimal width for the columns under which columns could not be resized. What I can suggest in this scenario is handling columnResizing event. In this event the current column width during resizing could be retrieved using desiredWidth option. If this width is less than your required value the resize method could be used to set column width to your minimum value and cancel the event. For example:

 {
              name: "Resizing",
              allowDoubleClickToResize: true,
              columnResizing: function (evt, ui) {
              var colKey = ui.columnKey;
              if (ui.desiredWidth < 50) {
                $("#grid").igGridResizing("resize", colKey, 100);
                 return false;
                          }
             }
}

I am also attaching a sample illustrating my suggestion for your reference. Please have a look at this sample and let mw know whether it helps you achieve your requirement.

If this is not an accurate demonstration of what you are trying to achieve please feel free to get back to me with more details.

I hoe you find my information helpful.
